This invention relates to springs and more particularly to an improvedspring assembly for use with beds, seats, couches and the like.

One object of the invention is to provide a spring assembly employingsprings which are interconnected so that said springs will be caused tocooperate efiiciently for supporting a mattress, cushion or the like.

Another object of the invention is to provide a spring assembly which isof such construction that the number of resilient elements is materiallyreduced without affecting the supporting surface.

In the drawings forming a part of my application:

Figure 1 is a top plan view showing a plurality of spring elementsarranged in rows and showing the connecting wire as it would appear inengagement with alternate coils of the rows of spring elements.

Figure 2 is a side elevation showing portions of the coils,

Figure 3 is a detail top plan view, on an enlarged scale, showing coilsof the connecting wire,

Figure 4 is a detail perspective view, on an enlarged scale, showing oneof the coil elements eX- tended to form the connecting wire,

Figure 5 is a side elevation showing one of the coil elements,

Figure 6 is a top plan view of the coil element shown in Figure 5,

Figure '7 is a side elevation of the coil element of Figure 5 andshowing certain of the coils of said element as they would appear bentto define a portion of the connecting wire,

Figure 8 is a top plan view of the coil elements seen in Figure 7,

Figure 9 is a side elevation of the coil element of Figure 5 and showingsaid coil element extended further to define an additional coil or loopfor the connecting wire, and

Figure 10 is a top plan view of the coil element shown in Figure 9.

Referring now to the drawings, wherein like numerals of reference willbe seen to designate like parts throughout the views, the numeral iindicates a close wound helical winding or coil. The coil l is formed ofwire which is resilient but is capable of being bent or deformed. Incarryin out the invention, two convolutions of the: coil or winding l,as indicated at A, are grasped between the fingers and are bentoutwardly to define straight portions A The following circularconvolution is then bent to define a short straight portion on the otherside of the coil or."

winding l. The operation is continued in this manner by successivelybending through to the left and to the right, alternately, of thewinding, and pivoted alternately about diametrically opposed points.After bending the convolutions in the manner described, a series ofjuxtaposed rings 2 is formed. The method of construction above describedis carried out by hand in order to enable the formation of the linkageto be better understood. It is obvious that machinery may be employed tobend the convolutions to define the desired linkage.

Figures 5 and 6 show in elevation and plan view, the helical windingfrom which the wire linkage will be manufactured. I0 is the upper end ofthe winding and II to I! are points of the winding spaced one andone-half convolutions apart and thus defining sections comprising eachone and one-half convolutions. The uppermost section (comprised betweenpoints 10 and H, is now bent 180 to the left around the point H, asshown by the arrow in Figure 7. Figure 8 is a plan view of Figure 7. Thesecond section (comprised between the points II and I2) together withthe first section, is then bent 180 to the right around the pointslZ asshown in Figure 9. Figure 10 is a plan view of Figure 9.

The operation is continued in the same manner by bending the wirealternately 180 to the left and right, around the points l3, l4, I5, l6etc.

In Figure l, the reference numeral 4 represents deep coiled springs. Thewire linkage 3, 6 and 1 engages the uppermost convolutions of thesesprings.

It is desired particularly to point out that the spaced rows of springsare interconnected by continuous wire which is bent so as to form ringshaped loops directed alternately to the right and to the left, saidloops being inserted alternately under the uppermost convolutions of thesprings in the left and right row, these two rows being thus securelyconnected by the continuous interlacing wire which also completes thesurface of the assembly between said rows of springs. This constructionis cheap to manufacture, is capable of easy mounting, and provides for avery advantageous resilient interconnection or bonding of the springelements at the surface of the device. Accordingly, uniform support fora mattress by the device will be assured.

Having thus described the invention, what is claimed as new is:

1. A device of the class described comprisin parallel spaced rows ofcoiled springs, and interlacing means connecting the upper terminalconvolutions of alternate springs of each row of springs, saidinterlacing means comprising a single continuous wire strand bent into aseries of circular loops lying in a single row in a horizontal plane,said wire being bent for interlacing one of the loops in one upperterminal convolution and said wire being bent in an opposite directionfor engaging another of the circular loops in an alternate oppositeupper terminal convolution, said interlacing means defining crossings onalternate sides of the successive loops, said interlacing means beinghooked at the crossings of the wire to the terminal convolutions forforming a cnnection between the spaced rows of springs.

2. A device of the class described comprising parallel spaced rows ofcoiled springs, and interlacing means connecting the upper terminalconvolutions of certain of the springs, said interlacing meanscomprising a continuous wire strand bent alternately clockwise andanticlockwise to ANDRE AUBY.
